To all 'whorn it may concem;

;na f be positively and aocurately fe I Be it known that I, AUoUs'r KRAUsE, of Boston, in the county of Suffolk and State of Massachusetts, have invcnted certain new and' useful Iniprovements in Feeders for Printing-Presses; and I hereby dcclare that the followin is a full, clear, and `exact description of t e same, reference being had to the accom any-ing drawings, forming part of this spec' cation. w

This invention relates to improvements in means for feeding forward sheets of paper to be rinted. i

ne ob'ect of the in vention is to so constl'uct a sheet eeding device for printing presses that a sheet placed upon said feedin device to the rolls.

Another object of the invention is to so construct a'feeding device of this nature that the' same may beadjusted'for sheets of different widths.

Another object of the invention is to improved feeding apparatus shown in relation` to parts of a printing press. Fi; 2, represents an end view of the same.l ig. 3, represents a bottom plan view ofA portions of the same. Fi 4, represents a sectional view, of parts o the same taken on line 4-4' Figv 1. -Fig. 5, represents an enlarged sectional view on line 4-4 Fig. 1 of parts of the mechanism to illustrate the means for cla'mpin the feeding arms to their slidable rods.

imilar characters 'of reference designate corresponding parts throughout.

` As shown m the drawings in its preferred form the improved feed'apparatus is shown in relation to the frame 10 of an Y usual construction which is'furnished wit the membersill 12, 13, and 14 and 15, in the latter of which the shaftsi of the usual feed rolls 16 and 17 are rotatabl mounted.

In bearings of t e frame members as' 11 is journaled the cam shaft 18 ada ted to be rotated in any usual manner and aving'the "i cam 19. On the frame member 10 ispivotall mounted the level' 20 furnish'ed at one,

si e of its ivot with the retractionspring 21 vwhich is a so secured to a fixed-part of the imountcd on studs exteuding from t machine whereby the action of said spring tcnds to hold the stud 22 of said levor 20 in contact with the cam 19.

To the member 13 is hingcd the food plate 6L 23 supported ut its free end on the frame members us 14 and having the parallel slots 24--24 beneath which are the lmrs 25--25 slidably supported by stirrups 20-20 which deend from the plate 23 and, at their u ipcr o en' s said bars have pcrforutions in which are engaged the arms 37- 27 of the bi'll cranks 28--28 which cranks are Jivotally lie under sideoftho late23. Attheupperedgeportion of the un er side of the plate 23 are mountcd the studs 29-29 on which is slidably mounted the bar '30 by means of its slots 31-31, the len th of which slots limits the movement o said bar to actuate the bcll crunks 28-28 with which said bar 30 is cugaged. The actuation of this bar is efl'cctod, under the swinging of the lever 20 by its cam 10, by means of bell crank lover 32 pivotally mounted at the under side of the platil 23 und pivotally connected with the lnu' t'U; one arm of this levcr being positionod to be uctuated by the levcr 20 and being furnishcd with the spring .'53 which is connected with the tud 34 fixed on said plate 23 whereby, under action of said spring 33 the lever 32 may be swung to so slii e the bar 30 and thus actuat'e the bell crank havers 28-28 to move the'slide bars 25 simultancously towurd the bar 30 until tlu'ir u Jor vnds bear against oo said bar 3 whi'h holds said upper cnds of vth'e bars 25 in pzictically oxact alinement.

Mounted on the shde liars 25 are the clamps 84 -34 havin the prcsscr blocks 35 and the squared shou ders 36 furnishcd with screw threaded perforations adapted to receive thescrews 37 whereby the clamps 34 are secured to the slide lmrs 25 and the sheet supports 38, having square openings adapted to fit the Shoulders 36, are secured to said clamps. The Sheet supports have 'screw threaded perforationsl as 39-39 in which the studs 40-40 are secured, these'studs being shown as securcd in such perforations at the. upperends of the` sheet supports but saidstuds ma when desired, lie removed there- Vfrom an may be similarly secured in such pei'forations near the lower end of said 'known means an the level' 2018 intermit;

spring ;{I; and the 'oar 30 is caused to move lengtlnrise fm its guide studs 29 -29 this ell`eetinfr the swinging of the hell eranks` 27 128 and '27-28 and the, sliding of the rods --5 with their ('.lamps 34 and the sheet supports 38 having the studs 4-0. lf a sheet as bo placed in position on the supports 38 said sheet is positively engaged hy tln` studs 40 and is msitively and aeeurateliV fed forward to and xatween the rolls 1G and 17 or their equiyalents. On the retraetive movement of the apparatus the ends of the rods 25-25 are. interrupted by the edge of the har which forms a gage aerurately positioning said rods 25 and the sheet engagmg meehanism carried therehy so that all i of the stnds *ML-A are in alinemeut at the eonnneneement of each forward movement and as these stnds 40 are moved forward simultaneously a certain distanee the Sheet plaeed in position must he fed forward acourately. i

The feeding device may he adjusted for feeding forward narrow shoets by the adat the under side thereof 01' heneath the same.

Having thus descrihed xny invention J elaim as new and desire to secure by Letters Patent I l. in a Sheet feeder foi` printing:r presses the eomhination with a. plate having a series of parallel slots, and a series of rods slidahly mounted heneath said plate in line with said slots, of a bar slidahly mounted at right an- ;les to the movement of said rods, connections between the said her and said rods for aetuating the rods when the bar is reeiproeated, said bar fonning an alining abutment for all of said l'ods, as described.

2. lu a sheet feeder for printing presses the combination with a plate having a series of parallel slots, guides at the under side of said plate in line with said slots, rods slid able in said guides, ehunps adjustahly mounted on said rods and extending through said slots, flat sheet supports extending in line ii'ith said slots and secured to said'elamps, and Sheet engaging studs removably mounted on said sheet su ports, of a bar slidahly f'nounted at the um er side of the said plate at right nngles to said rods, hell erank levers pivotally mounted on said late and angegmg said bar, and respective y en aglng said rods, a. spring retraetedhell eran pivotall' mounted on said plate` and eonneeted Wit justnieut of the elainps 34' on the rods '25 or i by removmg'the serew studs 40 from the serew threaded perforations at the upper ends of the sheet supports to the similar perforations 39-39 thereof.

By the hnging of the plate 23 said plate may he swung upward for the examination and adpistinent of the meehamsm located said slidahle` har, and means for intermittently aetuatmg said hellerank, as descrlhed AUGUST K RAUSE.
